Which graph is the graph of f(x)= x-1/x+2
Answers
Answer:
Step-by-step explanation:
Right bottom answer
The graph that represents the function f(x) = x - 1/x + 2 is graph (d)
How to determine the graph of the equation?The equation of the function is given s:
f(x) = x - 1/x + 2
The above function is a rational function, and it has its asymptotes at y = 2 and x = -2
From the list of given options, the graph d (bottom right) has its asymptotes at y = 2 and x = -2
Hence, the graph that represents the function f(x) = x - 1/x + 2 is graph (d)

Graph the line with the equation y=-2/5x+1
Answers
Answer:
Step-by-step explanation:
slope = -2/5
y intercept = (0,1)
The graph of the line y=-2/5x+1 is given below.
To graph the line with the equation y = -2/5x + 1, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is -2/5, which means that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 2/5 units. The negative sign indicates that the line slopes downward from left to right.
The y-intercept is 1, which is the point where the line crosses the y-axis.
To plot the line, start by marking the y-intercept at (0, 1) on the coordinate plane. From there, use the slope to find additional points. For example, if you move 5 units to the right (because the denominator of the slope is 5) from the y-intercept, the y-coordinate will decrease by 2 units, giving you the point (5, -1).

the graph shows the square root parent function. which statement best describes the function?
Answers
Answer:
Wouldn't it be D?
Step-by-step explanation:
A, B, and C both kinda are wonky and B definitely is wrong.
C is also wrong because it is not decreasing unless you are going backwards, which isn't how functions are supposed to be used.
A is false because it says when x is less than 0 (which isn't on the parent function) then it increases, which isn't possible.
D is your best bet.
The function is always increasing if you look at it.
It looks like it might stop, but will continue forever in a positive direction even though it looks like it would become a straight line eventually.
The function is increasing when x > 0
The graph shows the square root parent function is always increasing.
What is square root parent function?The parent function of a square root function is y = [tex]\sqrt{x}[/tex] . Its graph shows that both its x and y values can never be negative. This means that the domain and range of y = [tex]\sqrt{x}[/tex] are both (0, infinity).
As we can see from the graph where the value of x increases the value of function also increases or
We can say that for [tex]x_{1} < x_{2}[/tex]
[tex]f(x_{1}) < f(x_{2})[/tex] for ∀ x > 0
Hence for x > 0 the function is increasing.
